In some embodiments, the mounting hole includes a plurality of spaced apart mounting holes, and each of the plurality of mounting holes is formed by a loose core.
In some embodiments, internal threads are provided on the inner sidewall of the mounting hole.
In some embodiments, the chamfer is inclined at an angle of 40 ° to 50 °.
In some embodiments, the mounting hole has an inner diameter of 7mm to 8 mm.
Another object of the present invention is to provide a burner, which has a simple structure and low cost for the segment valve assembly.
The above purpose is realized by the following technical scheme:
a burner having a segmented valve assembly as described above.
Another object of the present invention is to provide a gas water heater, which has a simple structure and low cost.
The above purpose is realized by the following technical scheme:
a gas water heater is provided with the burner.
Compared with the prior art, the utility model discloses an at least including following beneficial effect:
1. the utility model discloses a section valve subassembly, its chamfer and mounting hole are loosed core and are formed, promptly at the fashioned in-process of section valve, chamfer and mounting hole form simultaneously, no longer need use other machinery to process from this and form the chamfer, and then reach the purpose that reduces process and manpower, reduction product cost.
2. Because the burner and the gas water heater have the segmented valve assembly, the burner and the gas water heater also have the advantages of reducing the working procedure and labor and reducing the product cost.

FIG. 1 is a schematic structural view of a segment valve according to an embodiment of the present invention;
fig. 2 is a partially enlarged view of a portion a in fig. 1.
Detailed Description
The present invention is illustrated by the following examples, but the present invention is not limited to these examples. To the embodiment of the present invention, modify or replace some technical features, without departing from the spirit of the present invention, it should be covered in the technical solution scope of the present invention.
The first embodiment is as follows: as shown in fig. 1 and 2, the present embodiment provides a segment valve assembly, which includes a segment valve 1 and a nozzle, wherein a mounting hole 100 is formed on the segment valve 1, a chamfer 101 is formed on an opening sidewall of the mounting hole 100, the nozzle is mounted in the mounting hole 100 through the chamfer 101, and the chamfer 101 and the mounting hole 100 are formed by core pulling.
In the sectional valve assembly of the embodiment, the chamfer 101 and the mounting hole 100 are formed by core pulling, that is, in the process of forming the sectional valve, the chamfer 101 and the mounting hole 100 are formed simultaneously, so that additional machining is not needed, and the purposes of reducing the working procedure and labor and reducing the product cost are achieved.
Referring to fig. 1 specifically, in the process of forming the segment valve 1, the root 200 of the mandrel 2 is inserted into a position where the installation hole 100 needs to be formed on the segment valve 1 correspondingly, and a lead angle is arranged at the joint of the root 200 and the mandrel 2, so that in the process of forming the segment valve 1, the chamfer 101 and the installation hole 100 are formed by die casting at the same time, and after the mandrel 2 is drawn out, the chamfer 101 is automatically taken out, so that additional machinery is not needed to be used for machining to form the chamfer, and the purposes of reducing the working procedures and manpower and reducing the product cost are achieved.
Preferably, the mounting holes 100 are arranged at intervals, the mounting holes 100 are formed by core pulling, and the mounting holes 100 and the chamfer 101 are formed by core pulling at one time, so that the production efficiency of the product can be improved, and the aim of reducing the production cost is fulfilled.
More preferably, the inner side wall of the mounting hole 100 is provided with an internal thread, and the internal thread is tapped by a tapping machine, so that the processing efficiency is high, and the purpose of reducing the production cost can be achieved. In addition, the internal thread can facilitate the tight connection between the mounting hole 100 and the nozzle, so that the nozzle is not easy to loosen.
In this embodiment, the inclination angle of the chamfer 101 is 40 ° to 50 °, preferably, the inclination angle of the chamfer 101 is 45 °, and the guiding effect is better, so that the automatic nozzle locking machine can conveniently screw the nozzle into the mounting hole 100 through the chamfer 101, and the fault alarm prompt of the automatic nozzle locking machine is reduced.
Further, the inner diameter of the mounting hole 100 is 7mm to 8 mm. Of course, the inner diameter of the mounting hole 100 can be selected according to design or use requirements, and the specific size of the inner diameter of the mounting hole 100 should not be considered as limiting the scope of the present patent.
Example two: the present embodiment provides a combustor having a segmented valve assembly as described in the first embodiment. The segmented valve assembly has the advantages of reducing the working procedure and labor and reducing the product cost.
Since the detail and the overall description of the segmented valve assembly are already given in the first embodiment, the detailed description is omitted herein for brevity.
Example three: the present embodiment provides a gas water heater having a burner as described in embodiment two. The burner as described in the second embodiment also has the advantages of reduced working procedure and manpower, and reduced product cost.
